Question

The no. Of trophic level in a food chain is limited give reason to justify this statement

the no. of trophic level in a food chain is limited because at every trophic level only 10% of energy or matter is transferred to next trophic level according to 10%law. therefore, after 3-4 trophic levels, so less amount of energy is left that after this no more energy can be transferred. hence no. of trophic level is limited.

Answer 2

The number of trophic level in food chain is limited because at each trophic level a large amount of energy is being utilized for the maintenance of organism and lost as heat. The energy keep on decreasing at each trophic level and only 10% of the energy is being passed to the next level.
